Garmin Descent X30 Dive Computer

Why Divers Choose the Garmin Descent X30

The Garmin Descent X30 is built for divers who want a large, easy-to-read computer without unnecessary complexity. Its 2.4-inch color display provides plenty of room for detailed dive information and customizable data screens, while four large leakproof buttons remain easy to operate underwater — even while wearing gloves.

Garmin's NDL Aware™ depth metrics provide real-time insight into how specific changes in depth may affect your remaining no-decompression limit. A dynamic depth chart also displays your dive history as it happens, helping you visualize where you've been and how your profile is affecting the planned ascent.

The X30 supports single-gas and multi-gas diving, including Nitrox and Trimix, with the ability to configure a bottom gas and multiple decompression or backup gases. Its Bühlmann ZHL-16C decompression model provides adjustable conservatism and custom gradient factors for divers who want greater control over their decompression planning.

On the surface, integrated GPS lets divers mark entry and exit locations and navigate to saved dive sites. Underwater, the built-in 3-axis digital compass provides precise navigation, while audible and vibration alerts help keep critical information from going unnoticed.
